computer stuff
The process to check main hardware components of the computer when it starts.
What is post?
A ROM chip on the motherboard that contains a small program to control the communication between the operating system and the hardware.
what is BIOS?
A memory chip that retains bios settings.
What is CMOS?
A UEFI security standard that ensures that a computer only boots an OS that is trusted by the motherboard manufacturer.
What is secure boot?
A term that describes one of the fundamental relationships found in electronic circuits: for a given resistance, current is directly proportional to voltage.
What is ohms law?
A RAID type that stores duplicate data on one or more other drives to provide redundancy, also called RAID 1.
What is RAID-mirroring?
A high-speed connection between the CPU and the Northbridge chip.
What is hyper transport?
A term to indicate the complete loss of AC power.
What is black out?
A RAID type that enables data to be distributed across multiple drives without redundancy, also called RAID 0.
What is RAID-striping?
A term to describe the dramatic increase in voltage above the normal flow of electrical current.
What is power surge?
A chip that performs the rapid mathematical calculations required to render graphics.
What is a graphics processing unit (GPU).
A RAID type that provides basic error checking and fault tolerance by storing checksums separately from data, also called RAID 5.
What is RAID with parity?
A term to describe a sudden increase in voltage that lasts for a short period and exceeds 100 percent of the normal voltage on a power line.
What is Spike?
A technique used to make a processor work at a faster speed than its original specification.
What is overclocking?
A term to describe the interference on a power line from generators and lightning.
What is noise?
A RAID type that provides fault tolerance up to two failed drives, also called RAID 6.
What is RAID with double parity?
A technology to store data across multiple storage devices for availability, reliability, capacity, redundancy, or performance improvement.
What is Redundant Array of Independent Disks (RAID)?
A computer bus interface for connecting ATA hard drives and other storage devices to the motherboard inside a computer.
What is Serial ATA (SATA)?
A standard for connecting peripheral and storage devices in a daisy-chain fashion.
What is Small Computer Systems Interface (SCSI)?
A fact sheet that summarizes information about material identification, including hazardous ingredients that can affect personal health, fire hazards, and first-aid requirements.
What is Safety Data Sheet (SDS)?
A term that describes the state of reduced voltage level of AC power that lasts for a period of time.
What is Brown out?
A CPU technology that enables multiple pieces of code (threads) to be executed simultaneously.
What is Hyper-Threading?
A CPU architecture that uses a broad set of instructions, resulting in fewer steps per operation.
What is Complex Instruction Set Computer (CISC)?
A technique used when the processor runs at less than the rated speed in order to conserve power or produce less heat.
What is CPU throttling?
A CPU architecture that uses a relatively small set of instructions.
What is Reduced Instruction Set Computer (RISC)?
